Injunctive Relief

The consent decree requires Ryland to implement a compliance program that will ensure adequate management and oversight of construction sites and compliance with National Pollution Discharge Elimination System (NPDES), stormwater permits. The compliance program includes:

  • Designation of a national stormwater compliance manager who will oversee the compliance program company wide
  • Designation of trained and qualified site-level and division-level stormwater compliance managers for each site who will be responsible for compliance at that site
  • Specific requirements for site-specific Stormwater Pollution Prevention Plans
  • A requirement to conduct and document a pre-construction inspection and review at every site prior to commencing construction activity
  • Requirements for routine site inspections including the use of standardized forms approved by EPA which require Ryland to document completion of all responsive actions taken to achieve or maintain compliance at a site
  • A requirement that the division-level stormwater compliance manager conduct an oversight compliance inspection and review at every site within his/her division once every calendar quarter
  • Implementation of a stormwater training program for Ryland employees that includes annual refresher training for stormwater compliance managers
  • Implementation of a stormwater orientation program for contractors
  • A requirement to submit national compliance summary reports to EPA; the national compliance summary reports are based on each division’s summary of its quarterly oversight inspections and reviews

Pollutant Reductions

As a result of this settlement, EPA estimates the sediment discharged in stormwater runoff will be reduced annually by 261 million pounds from Ryland sites nationwide, with a reduction of approximately 11.6 million pounds per year within the Chesapeake Bay Watershed.

Health and Environmental Effects

Discharges of stormwater runoff, including runoff from construction sites, can have a significant impact on water quality.  Construction activities alter natural landscapes.  During construction, earth is compacted, excavated and displaced, and vegetation is removed.  These activities increase runoff and erosion, thus increasing sediment transported to receiving waters.  In addition to sediment, as stormwater flows over a construction site, it can pick up other pollutants such as debris, pesticides, petroleum products, chemicals, solvents, asphalts and acids that may also contribute to water quality problems. 
Sediment-laden runoff can result in increased turbidity and decreased oxygen in receiving waters, which in turn results in loss of in-stream habitat for fish and other aquatic species. 

Sediment can kill fish directly, destroy spawning beds, suffocate fish eggs and bottom dwelling organisms, and block sunlight resulting in reduced growth of beneficial aquatic grasses.  In addition, sediment can impact the treatment of drinking water resulting in higher treatment costs, and can result in the loss of drinking water reservoir storage capacity and decrease the navigational capacity of waterways.
